Turnigy introduce the Min Power Distributor UBEC (Red) suited to 30cc plus gas powered models.
This unit has great features, which include: Dual battery input, 5v isolated linear RX BEC, 8 channel RX input with dual outputs on each channel - simplifying dual servo control surfaces.
Great inclusions are the independent 5V linear regulator providing a separate power source for the receiver, optically isolated CDI power & in built remote ignition kill. Receiver, Servo & CDI power sources are completely isolated from each other.
Three selectable UBEC operating voltage options (via Jumper):
Direct connection: uses 5V- 6V input to supply power - voltage pass through from battery input to Receiver
Voltage drop 0.5V: Reduces a 6v input to 5.5v
Voltage drop 7805: use 7.2V- 8.4V input to supply 6v regulated power
This is the first Power Distributor system to securely nest the receiver within the power distribution 'block' thereby shortening cable runs, adding protection to your all important receiver & speeding set up time.

I got one of these a few months back and was very impressed. On closer inspection I noticed that this is the same as a premium power hub that sells for far more money than the Turnigy brand HK is selling.
The only odd thing I've noticed with it is that when the ignition cut-off is set up, the hub ALWAYS has the ignition off regardless of the switch position on the transmitter. I was able to solve this by activating a switch warning for the ignition cut-off on my transmitter that forces me to make sure the switch is in the "off" position when I turn on the radio or activate the model profile. Had I not been able to do that I would have been REALLY annoyed by this.
Receiver voltage is a pass-thru, but it's not really a problem since almost all modern receivers will take up to 10.5V and (unless you're using UHV 11.1V servos) servos all run on 8.5V or less.
All told, this is a good quality power hub and I will be buying more of these as needed.Just want to say the tabs for the grommits are a bit weak on the new plastic housing and one has so far broken of on my 55cc plane, so in that respect I prefer the older version.WARNING! WARNING! WARNING!
The circuit diagram that comes with this product clearly shows 5v to servo's.
However upon using 2 X 3s lipo's for input voltage in became clear that the input battery voltage for main power is the same as the voltage that is outputted to servo's.
So if you use s3 11.1v for power this is the voltage that is output to the servo's
I found this out the hard way and ended up instantly burning out 5 X 70 Digital servo's
Total cost on burnt out servo's 350
The only 5v bec is to the receiverPurchased in early May/2015 so I can assume this is the latest version. There are conflicting specs between posted and instruction sheet however to clarify there is no internal rx voltage regulator. What you put in for voltage is what you will supply to the rx. Not an issue for me as I already own a good quality 20 amp BEC to be used with a 2S LiPo as the power source.
The buses are rated at 20 amps in the documentation supplied with the unit.
The internal CDI circuit worked as advertised and is a nice bonus at this price point.
One very good feature is the on/off switch. The unit is designed to turn on when the switch is open or simply not plugged into the unit at all. Should the switch fail in flight it will not turn your power supply off.
Over all I am satisfied this unit will be a solid performer for my 50cc gasser at a very good price point.
KRI have received the above pictured panel and it is a simple straight through power distribution panel, whatever power goes in the same comes out. (Three selectable UBEC operating voltage options (via Jumper): There is not a jumper wire to change the output voltage. The RX voltage is a constant 5 VDC. Hobby King has miss represented this item. I do believe the device will work fine but it is not as advertised.I just got this red power distributor board and here is what I found. Knowing ahead of time this borad passes the power from the batteries striaght to the servo's I opted to use Life batteries. I am getting the 6.7v from the batteries power regulated to the reciever at 4.9v and I am getting 6.7v to all 8 servo's connectors on the board. I am only using a 7 channel reciever so I am using a servo extension on the board from the channel 8 position to supply 4.9v to the CDI power input of the board. That way I will not need an extra battery for my CDI cut switch. I than ran a servo extension from the position 9 on the board to channel 7 of my reciever so when I turn on channel 7 that turns on the CDI for my ignition and this setup works perfectly. I have it on a 82" Skyshark P-40 with a 50cc XYZ engine. Great value for the moneyI have 4 of these now and they work faultlessly, I use them for HV setups ie: 7.2v lipo in and 7.2v to servos and receiver, I even have one in a 35pcnt aerobatic plane.
As a pass through power box these are perfect. I would give 10 stars if I could.Muito boa esta Powerbox, bem facil de entender as ligacoes, Nao utilizarei o kill switch dela, no mais parece ser muito bem feita.Gesamtbewertung 10/2/2012
ich habe 2stck davon.achtung nicht lipotauglich.Spannung auf servos mit 2s 6.6volt.cdi schaltung keine fuktion.ansonsten ok.
Hallo Hans, warum
bist du der Meinung es ist nicht Lipo tauglich ??? Mit 2S sollte es doch passen.This is merely a glorified power distribution bus.
It has a regulator for the receiver ONLY and direct passthrough for the servos.
You MUST use a battery that puts out what the servos can handle.
2S LiFe packs work best with this unit.
